Anniversary edition is literally just SE but with some Creation Club DLC content. Unless you're referring to the specific 1.5.97 version of SE. It doesn't make much of a difference anymore, but if you want to use 1.5.97 you have to get that version from the Steam depot if you don't have it installed at the moment. Certain mods and dependencies also are specifically made for AE or pre-AE versions, like the unofficial patch or script extender, but otherwise almost all mods should work with either version. If you download a mod that doesn't seem to load in on 1.5.97 you can open it in SSEdit and change the version number in the .esp/.esl header section from 1.71000 to 1.70000.

I think most new mod releases are made with the assumption that players will be using post-AE versions but it all just comes down to whether or not you want Creation Club content in your game or not. It's probably easier to mod post-AE versions now than pre-AE versions but it wouldn't make much of a difference. I use 1.5.97 (pre-AE) myself and haven't had much issue.

I've made some Skyrim mods for personal use, but nothing real impressive. Most of them are mods to overwrite other mods. Just an NPC replacer, a custom follower/wife, something to change the music from a custom house I downloaded, and a script edit to remove the list of forbidden actors from sexlab, although I don't use that one anymore. None of these are published, mostly because they aren't worth publishing or they would violate permissions/ToS if I did upload them.

I also made a few Morrowind mods and even uploaded one onto Nexus but again it's all really minor changes that anyone could probably do themselves.

There aren't any other RPGs that I've made mods for, simply because they're not as easy to mod as Bethesda games and I haven't had any modding ideas for them.
